4/23/20156 Background Research Use reliable resources such as Britannica Online, EBSCO, and reference books from the library. GISD provides free access to Britannica Online and EBSCO. See your school librarian for details. Write a 2-3 page report on the topic you have chosen to ensure that you have adequate knowledge to accurately conduct and evaluate your experiment.

4/23/20157 Background Research Write the report in your own words. DO NOT copy and paste information from the Internet! Cite all references in a bibliography. Note: Encyclopedia Britannica Online provides full reference citations on every page!

4/23/20158 TITLE Try to make your title catchy and clever. Make a list of title ideas in your notebook as you work on your project. Later you can decide which one is your favorite. Your title should be in large letters to catch the judges’ attention.

4/23/20159 INTRODUCTION What “sparked” your interest in your idea? Do some research on your topic— check out books from the library and look at reliable websites to learn more about your topic. You should explain how you became interested in your question and what results you think you might discover from your experiment.

4/23/201510 INTRODUCTION When my family takes our ice chest to the lake, the ice always seems to melt quickly and our soft drinks do not stay cold. I would like to investigate different shapes of ice cubes to discover which shape will last the longest in our ice chest.

4/23/201511 Experimental Design: Steps for Scientific Method I.State the Problem in the form of a question. II.Make sure the question is testable. (Something that can be observed or measured)

13
4/23/201513 Experimental Design: Steps for Scientific Method II. State your Hypothesis. A hypothesis is an educated guess about the answer to the problem based on observations. It should be stated as an “if…then…” statement that predicts the outcome of the test.

4/23/201514 HYPOTHESIS If I freeze ice cubes that all have an area of 2 inches square, but one is in the shape of a cube, one is the shape of a rectangle, and one is the shape of a sphere, then the sphere shaped ones will melt the slowest.

15
4/23/201515 Experimental Design: Steps for Scientific Method III.List all Materials used in the experiment. This should be a very specific and detailed list.

17
4/23/201517 Experimental Design: Steps for Scientific Method IV.List your Procedures in a step-by-step format. You must design an experiment that establishes and identifies a control. All conditions in the additional tests must be measurably identical to those in the control, except for the one independent variable that you are testing.

18
4/23/201518 Procedures 1.Completely fill the 2 cm 2 cube with water. 2.Repeat step 1 using the rectangle. 3.Repeat step 1 using the sphere. 4.Place all three containers side by side in the freezer at a temperature of 0 degrees Celsius. 5.Close the freezer door. 6.Allow containers of water to freeze for 6 hours. Do not open the refrigerator door during this time.

19
4/23/201519 Procedures 7.Remove all three containers from the freezer at exactly the same time and set them side by side on the counter. Turn on the timer immediately. 8. Observe the containers every 5 minutes until the ice has completely melted in each. As it gets close to being completely melted, observe every minute. Record the time in minutes that it took to melt the ice. 9. Repeat this entire experiment 9 more times following the identical procedures from above.

4/23/201520 Experimental Design: Steps for Scientific Method V. Record your Observations in a Data Table. Make sure to label all units of measurement.

25
4/23/201525 Experimental Design: Steps for Scientific Method VII. Provide a Conclusion to the experiment based on the results indicated. The conclusion should answer the question posed in the problem.

26
4/23/201526 Conclusion The best shape of ice to buy for filling an ice chest would be spherical because it melts the slowest. This is probably due to less surface area being exposed, resulting in a slower melting rate.

27
4/23/201527 Future Research Now that I know which shape of ice melts the slowest, I think that I should test the effects of using different shapes of ice on the water temperature in the ice chest to see which one will really keep my beverages cold the longest.
